(Cl. 2li-53) Clalml.

invention is to provide a window so equipped asto give desired ventilation without draft, and without, of course, detracting from the light-admitting capabilities of the window.

In accordance with the present invention a window is provided that can be adjusted to any degree within reason between a fully opened and a fully closed position for providing the desired ventilation.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is an elevational view oi' the window looking at the same from theouter side thereof.

Figure 2 is a longitudinal sectional view taken substantially on the line 2-2ovf Figure 1.

Figure 3 'is a view similar to Figure 2 but with the window in an open position of adjustment.

Figure 4 is a horizontal sectional view through the window in open position of adjustment.

Figure 5 is a detail sectional view taken substantially on the line l-l of Figure 1.

Figure 6 is a detail sectional view taken substantially on the line 8-8 of Figure 4.

Figure 'I is a perspective view of the bottom or lowermost transparent slat, and

Figure 8 is a similar view oi' a second form of slat used in accordance with this invention.

Figure 9 is a fragmentary detail view showing two of the side members formed with the seats for the slats.

Figure 10 isa view of the upper latch means.

Referring more in detail to the drawings, it will be seen that 5 indicates generally a window casing that is more or less of conventional type and structure.

In accordance with the present invention there is fixedly mounted in the window casing I a frame 4, embodying a toprail 6, side rails 1, and a bottom or base rail l.

Also mounted within the casing 5 for movement vertically and also horizontally toward and away from the frame 4 is a shiftable frame 3, embodying a top rail or frame member 3, side rails Il), and a bottom or base rail II.

Each of the side rails 'I of the first-mentioned frame indicatedgenerally by the reference numeral 4, is notched at intervals to provide on the inner face of each side rail 'I a vertical series of spaced shoulders I2 that complement shoulders I3 provided on vertical cleats I4 suitably mounted on andsecured to the side members I0 of the second-mentioned frame, and designated by the reference numeral I.

Between each pair of shoulders of a side member I4 the inner edge of said member slopes upwardly and towards the unnotched edge of the member to i'orm a seat I3 for an end of a slat and between each pair of shoulders I2 of each side member 'I the edge of said member 1 slopes upwardly and towards the member I4 to provide aV sloping seat I2' for an end of a slat. These slats are shown at I5 and I8, the slat I8 being the lowerrnost one and these slats are of preferably transparent material such as glass. As shown the ends of the slats at the lower edges engage the lower shoulders I2 and at their upper edges the shoulders I3 with said ends oi the slats resting upon the seats I2" and i3 when the device is closed. Said slats I5 and IB have their ends extended as at I I for engagement with hook-like lugs I8 provided on pressure bars I9 suitably mounted on the side rails I0 of frame 3 adjacent to and paralleling the cleats I4. The pressure bars I8 have limited sliding movement on the frame rails I Il between the blocks I0' attached to the rails I0, and cleats I4 and said bars I8 are yieldably urged downwardly for maintaining positive frictional engagement of the keeper lugs I8 with the slats I5 and IB, through the medium oi' coil springs 20 suitably anchored on the frame 3 adjacent the bottom thereof and secured to the lower ends of the pressure bars I9.

The frame'l and associated parts are normally urged into the window-closing position shown in Figure 2, or in other words towards the frame 4 through the medium of upper and lower pairs of suitably provided coil springs 2i, 22. The springs 2l, 22 at one end are suitably anchored to the casing l and at an opposite end are suitably secured to the side members Ill of the aforementioned frame 3.

To facilitate manipulation of the frame 3 and associated parts for positioning the slats I5 and Il at the desired angle, or in other words for placing the window in the desired position of ad justment, there is provided on the bottom member I I of the frame 3 a handle member 23 and on the top member 9 of the frame 3 a handle 28.

' 3 inwardly away from the frame 4 and downwardlyto, for example, the position shown in,l

Figure 3 for positioning the slats Il and I! as 10 therein shown, whereby to permit Aproper ventilation.

Any suitable means may be provided for securing the frame 3 and associated parts in the desired position of adjustment. In the present instance such means is shown as consisting of slidable bolts 25 suitably connected at their inner ends with the aforementioned handle 23 to be projected or retracted incidental to a proper turning movement of the handle 23. The bolts 25 are slldably mounted on the rail member Il oi' the frame 3, and for cooperation with these bolts there are suitably mounted within th-e window casing 5, at the base thereof, segmental keeper plates 26 provided with series of aper- 2 tures 2l with which the outer or free ends of the bolts are engageable in an obvious manner.

Also to positively secure the window in a closed condition, the handle member 23 is formed integral with a pivoted latch member 28' that is cooperable with a keeper plate 29 suitably mounted on the top member o the casing 5 interiorly of the casing as will be clear from a study of Figures 2 and 3.

It will also be noted that the upper edge o the frame member 8 and the outer edge lo! the frame member H are beveled or otherwise complementarily formed as at 29 and 30, respectively, so as to nicely contact when the window is in a fully closed position, thus further insuring against draft when the window is in said osed condition.

c] Also to limit relative movement of the frame 3 there are provided at opposite sides of the cas- 4 ing 5 lengths of chain or the like 30', anchored at one end to the sides of the window casing 5, interiorly of the casing, and suitably secured at the other end thereof to the side members lli of the frame 3. 5 It will be apparent that a window embodying` the features of construction, such as herein described, can be opened to practically any position of adjustment for admitting into the interior of the room or building the desired amount of air without causing draft.

It is thought that a clear understanding o! the construction, utility and advantages of a window embodying the features of the present invention will be had without a more detailed description.
